Bean curd production method with no waste water discharge

Abstract

The bean curd producing process adopts soybean and peanut as protein material and has no waste water drainage, less loss of nutritive matter, low water consumption, low power consumption, high output, no pollution, low production cost and high product quality. The production process includes dry sorting of soybean and peanut, cold oil squeezing, crushing bean residue, regulating milling water amount to control soybean milk concentration and adding coagulant, and may produce bean curd, bean milk and other products. The present invention can reach the effects of raised economic utility, rich nutrients in product and no environmental pollution.
